use COPY --chown to stage repo (docker 17.09)

See original GitHub issue

Right now, we copy and chown the repo in two layers, which doubles the size the repo takes up in the env. This used to be required. Docker 17.09 adds support for COPY --chown to do it in one layer. So we can do this when it becomes okay to require docker 17.09 as the base version.

Me and @jhamman found out that version of docker used by GKE does not support this yet, so the default install of BinderHub can’t use it (since it uses the same docker as the underlying cluster)
